The most common issue with printing is 'page scaling' which can be set in the print dialogue box. Page scaling should be set to NONE or 100%
If using Adobe Acrobat ensure to select [Actual Size] under Page Sizing and Handling
Print Area = Maximum
Scale to fit page size = No Scaling or A4
Page Margins = Minimum
Reduce/Enlarge = 100%
If using Preview ensure to select Scale = 100%
